Title: Pwm signal generating circuit
Inventor: KINOSHITA HISASHI
IPC: H02P7/29
Filed: 1991-04-09
Abstract: PURPOSE:To improve the resolution with simple circuit constitution in a PWM signal generating circuit for a servo controller and an inverter. CONSTITUTION:A timer 6 loads the output of a timer value setting circuit 7 and is latched when the output (e) of an EXOR gate 5 is at a low level. When the output of the gate 5 does to a high level, countdown is started synchronously with the rise of an input clock signal (b) and when a set time value reaches 0, the timer outputs a latch signal (f) from a ripple clock terminal. The input pulse signal (a) is changed in a 2nd shift register 2 and an output signal (d) is changed synchronously with the rise of the signal (f). In this case, the output of the gate 5 goes to a low level and a timer value is loaded to the timer 6. Then an AND gate 3 receiving the output signal (c) of a 1st shift register 1 and the output signal (d) of the register 2 generates a 1st PWM signal (g) and a NAND gate 4 generates a 2nd PWM signal (h). The 1st PWM signal C and the output signal (d) at a high level represent an ON command and those at a low level represent an OFF command. The resolution of the output signals (g), (h) is improved by increasing the frequency of the signal (b).

Title: Synthesizing apparatus for high-and low-priority data in video-signal processing system
Inventor: ARUFUONSU ANSONII AKANPORA
IPC: H04N5/44
Filed: 1992-02-26
Abstract: PURPOSE: To enable excellent image reception by putting HDTV data, which are divided by two kinds of high priority and low priority according to importance and then compressed and transmitted, together again hierarchically on an image reception side. CONSTITUTION: This is a device which decodes a transmit HDTV signal as data distributed to high and low priority channels (HP and LP). The high and low priority data are obtained from blocks of compressed data 10 which are coded hierarchically, and the data in the blocks are distributed (11) to both the high and low priority channels according to the importance of image reproduction. This device has a circuit which discriminates between the high and low priority data and segments them by corresponding blocks (20-25), and further recombines the high and low priority data hierarchically into a compressed video data stream (26).

Inventor: OZAWA KUNIAKI
IPC: G11C29/00
Filed: 1986-04-04
Abstract: PURPOSE:To shorten a diagnostic time by dividing a large scale circuit gradually and narrowing down a trouble range. CONSTITUTION:For example, an observation signal line 211 is assumed to have a fault value from a test result storage file 502 obtained by a general LSI tester. An observation point determining device 501 selects signal lines 208 and 210 as new observation points so as to check which of signal line the fault value is propagated through, and network list information is read out of a file 503 indicting the constitution of a logic circuit diagram and utilized. The file 503 is utilized by a fault range dividing circuit 504 to draw a signal skeletone diagram. Then, the fault range dividing device 504 utilizes the signal skeletone diagram as to new observation points 208 and 210 to find an arrival set and a common arrival set. Those results are as shown arrival sets 31 and 32 and a common arrival set 33 and the fault range is divided into fault ranges 41-43 correspondingly.

Title: Device for displaying operating number of sequence controller
Inventor: KAKIMOTO EMI
IPC: G05B23/02
Filed: 1991-04-10
Abstract: PURPOSE:To easily analyze the abnormality of a sequence controller when the controller is in abnormal. CONSTITUTION:When an address given from an input/output bus line 16 is a prefixed address indicating an operating number, a discrimination circuit 17 outputs operating number data (a) corresponding to the address. A latch circuit 19 latches the data (a) outputted from the circuit 17 when a latch inhibiting signal (c) is not outputted. An abnormality detecting section 22 reads out a proper operating number at the latching time whenever the data (a) are latched to the circuit 19 from a sequence storing memory 23 and compares the read-out number with the operating number data latched to the circuit 19. When the number is not coincident with the data, the section 22 turns on a sequence abnormality indicator lamp 25 and simultaneously, outputs the latch inhibiting signal (c). A numerical display driving section 20 displays the operating number data latched by the circuit 19 on a numerical displaying section 21.

SOLUTION: In a heating system in which an electric heater 2 is energized at night time to store heat in a heat storage body 1, and the heat is radiated during the day time for heating, the air which is brought into contact with the heat storage body 1 to be turned into the hot air after the heat exchange, flows out of an air outlet 6b, and heats a metallic plate 10 while passing through a passage between an external case 5 and a heat insulation material 3, and a bi-metal 8 is deformed by the heat of the metallic plate 10. When the temperature of the hot air is dropped, the temperature of the metallic plate 10 is also dropped, and the temperature of the bi-metal 8 is soon dropped to the temperature of the hot air.  The deformation of the bi-metal 8 becomes larger as the temperature becomes higher, and the opening of the air outlet 6b to be adjusted by a damper 7 becomes large when the temperature is low, while the opening becomes small when the temperature is higher, and the appropriate heat radiation is controlled according to the temperature of the hot air.
